Windows 10: Win 10 licensing from Win 7 OEM key

We have a large number of Dell systems in our organisation, currently on windows 7 PRO licensed with Dell OEM. Can we use the windows 7 or 8 Dell OEM key embedded in the motherboard to upgrade the system to Windows 10 PRO free of charge?

AFAIK, OEM licenses will have a Product ID that usually contain "OEM" within it - it can be found under Control Panel > System > Windows Activation (usually).

Hope this is not against the rules. If you do a clean install of Windows 10, it may, (has for me) accept a Win 7 OEM key and activate.

 

How to move Win 7 license over to a new rig?

I know this topic has come up before. First, clear the air... this is a legit Win 7 Ultimate install/key.

I'll be building a new system and want to uninstall Win 7 from the current system and reinstall with a new MB, CPU and memory. I want to do a clean install, this one was buggered when Windows Update was running (I didn't know at the time), and I was trying to uninstall Norton. It's not pretty.

I've got 2 problems:

• I don't know the original key (I have used Belarc Advisor before with success, are there any other tools?)
• I don't know exactly what flavor of Win 7 I have on this PC. I don't even know if it's retail or OEM. How do I find what image I need?

Thanks in advance...
